ing magma ascent through the overlying crust can strongly imprint on the chemical signature of OIB. In particular, the isotopic composition of the major element oxygen, which is commonly measured on olivine minerals, records such processes. Genske and colleagues demonstrate that the variability observed in the oxygen isotope data is strongly correlated with the chemical evolution of the minerals, hence excluding lower ratios to be representative of their mantle source. Instead, they suggest that most of the oxygen isotope variability recorded in olivine from the Azores is due to recent contamination processes, and this may be true for OIB in general.


Mantle 3He and CO2 degassing in carbonic and geothermal springs of Colorado and implications for neotectonics of the Rocky Mountains
Karl E. Karlstrom et al., Dept. of Earth and Planetary Sciences, University of New Mexico, Albuquerque, New Mexico 87131, USA. Posted online 20 Feb. 2013; http://dx.doi.org/10.1130/G34007.1.

Geochemical analyses of many of the famous hot springs of Colorado show that these waters carry helium and carbon dioxide gases that originated in Earth's mantle more than 40 km (ten miles) below the surface. Mantle degassing is unexpectedly widespread across much of the Colorado Rockies but is highest in regions underlain by warm, buoyant mantle. This paper by Karl E. Karlstrom and colleagues shows that hot springs, carbonic springs, and CO2-rich regional gas fields are surface vent regions for neotectonic degassing of mantle volatiles through continental regions that are undergoing active tectonism and epeirogenic uplift. The total CO2 flux through these springs constitutes a small but persistent contribution to the CO2 budget and is important to understand for studies of carbon sequestration and natural leakage.
